The musical pair spent some time at John’s secluded 15-acre estate in Bozeman, Mont. — but decided to venture out during their stay earlier this month.
The couple were spotted at a concert to watch local Johnny Cash tribute band, The Cook Hard Cash Show, in nearby Livingston.
“Katy and John listened to the band, danced for a little while and then sat by the bar,” an eyewitness tells Life & Style. “They seemed very in love and affectionate.”

It seems that Katy, 28, and John, 35, who have been dating since October, are very happy together.
“For the first time in my life I don’t feel like I’m in a celebrity relationship,” he shared. “I really don’t. I’m not in a high profile – I know it’s high profile. It’s hard to explain … For me it feels like something that’s very human.”
Looks like John has officially put his bad boy days behind him!
